Trading won games is about as cool as the surface of the sun...

no its not... ask for a reroll

who cares, do whatever you want

YOLO

Just ask for a reroll.

If you've not done anything with it yet and still have the gift in your inventory, give it back to the giveaway maker, and ask him to request a re-roll so someone who does want it can play it. If you don't activate a win in your account, you risk a ban, and a lot of criticism from members of the community who see you didn't activate 1 of your wins but don't know why.

Whatever you do choose to do, never re-gift anything you win. That's the surest way to get in trouble.

Do a reroll if u're really that kind.

reroll or face a ban. Simple as that.

You want to turn down Bioshock?

Well, if you plan to keep it, you have 6 days to activate the game on your account. If you don't activate it, you'll be suspended for it.
